MDG-200 Radio Altimeter

MDG-100 Radio Height Setting Device

The MDG-100 radio altimeter operates in the C-band and adopts a pulse Doppler working system. Its sensitive device is of the heterodyne type, and the circulator at the antenna terminal uses a transceiver common-mode design. With mature technology, this altimeter is installed on missiles and serves as a control component for altitude fuzes. It features capabilities such as high burst altitude, strong adaptability to high falling speeds, and excellent performance in resisting ground clutter and sea clutter. Additionally, it employs pseudo-random pulse modulation technology: the pulse period varies randomly within a specified range, making it difficult for jammers to identify the initial modulation pulse of the fuze signal and further predict the delayed pulse. This design effectively enhances the altimeter’s resistance to active interference.
